I personally think it's a rumour based off of that one unreliable article and repeated by small unreliable (and international) websites. The original was likely fancasting wishful thinking, or the studio dropping names to hype up competition - but it never claimed he auditioned for it.
I also said in a different thread that I somehow doubt he'd be up for it, unless it's a really meaty role... and it's likely not, being a supporting and Disney. Besides, it's quite similar in vibe to Laurie (dreamy floppy haired good guy, a Prince charming) and I don't see him rushing so soon to that role again, even if it is high profile and good money.
Dunno, seems like his next film would be gritty and realistic. And/Or for a top tier director.
I don't see the appeal for him, unless he really really wants to dance and sing and even then there are surely more challenging options out there.
